Definitions
- the invention relates to a closure for a liquid Fuel receiving tank of a motor vehicle according to the preamble of claim 1, as known from EP-A-997337.
- closures are well known in practice, in a first embodiment with at the Inner lateral surface of the filler neck provided sealing surface and in a second embodiment with at free end face of the filler neck provided sealing surface. Both embodiments have also proven themselves.
- the seal is mainly intended to prevent the escape of liquid Prevent fuel from the tank. At the same time but should also the escape of gaseous or volatile Fuel components are suppressed.
- Just the latter für has a greater importance in recent times obtained; in fact, they lead when refueling inevitable manipulations of the fuel nozzle too Damage to the sealing surface of the filler neck. A safe suppression of gas emissions from the tank interior is no longer guaranteed.
- the closure is a Main weak point forms, depending on the damage of the Sealing surface there up to 80% of the total emissions of the Fuel system can occur.
- the invention is based on the object, a closure to develop for a tank of a motor vehicle, in which Damage to the parts causing the seal a fuel nozzle are no longer possible.
- the inventive solution to this problem is at a closure of the type mentioned in that in Fill in one with its from the free end of the filler neck opposite end attached to the filler neck Protective pipe section for the sealing surface of the filler neck is provided and the protective pipe section together with the Einglallstutzen a receiving chamber for the pipe socket of Rotary closure element forms.
- the filler neck provided sealing surface is the free end of the protective tube section approximately in the Level of the free end of the filler neck arranged.
- the protective pipe section does not end before Filler, so that the protective pipe section together with the cover organ another chicane for the forms liquid fuel.
- the Lid organ with a lid collar close to the Pull down the sealing rings to the latter also at the The filler neck removes the lid organ from damage protect.
- the arrangement preferably made such that the free end of the Protective pipe section the free end of the filler neck surmounted.
- the filler neck at a distance from another outer protective pipe section to surround, its free end approximately in the plane of the free End of the inner protective tube section is located and the together with the filler neck a receiving chamber for forms an outer collar of the lid member.
- the respectively formed Accommodating chambers at its lower end a Have fuel passage to possibly in the Accommodating chambers in a fuel Drain possibility to give.
- This can be, for example be achieved in that the protective pipe section only connected at spaced points with the filler neck becomes.
- Filler neck, the protective pipe sections, the pipe socket and / or the outer collar at their free ends crowned training and / or with introductory bevels provided to the placement of the rotary closure element to facilitate the filler neck.
- the closure shown in Fig. 1 is for a with liquid fuel tank to be filled Motor vehicle determined.
- a rotary closure element 1 which on a Filler neck 2 of the tank is releasably secured.
- This Rotary closure element 1 has a to a cover member. 3 subsequent, projecting into the filler neck 2 Pipe socket 4 on.
- the rotary closure element 1 or Lid member 3 has on its outside a Tamper crossbar 5 on.
- the rotary closure 6 can by a screw connection or a bayonet connection between the free end 15 of the filler neck 2 and the this superior lid collar 7 of the lid member. 3 be realized.
- Pipe stub 4 On the outer circumferential surface 8 of Pipe stub 4 are two on the inner circumferential surface 9 of the Filler 2 fitting sealing rings 10 in shape an O-elastomer ring spaced from each other. There is an easy possibility to one of the to dispense two sealing rings 10.
- the Inner circumferential surface 9 of the filler neck 2 and the associated outer circumferential surface 8 of the pipe socket 4 can also be conical or tiered to the Sealing function only at the end of closing ensure and so the sealing rings 10 a longer To give life.
- This protective pipe section 11 is with his from the free end of the filler neck 2 opposite end 12 attached to the filler neck 2, z. B. welded. Together with the filler neck 2 forms this protective pipe section 11 a receiving chamber 13 for the pipe socket. 4 of the rotary closure element 1, so that the sealing ring (s) 10 and inner surface 9 of the filler neck. 2 formed seal the mechanical attack of fuel nozzles completely withdrawn.
- the free end 14 of the protective tube section 11 is located in the Plane of the free end 15 of the filler neck 2, d. H. goes as far as the free end 15 of the filler neck 2. Incidentally, it can be seen in FIG. 1 that the Filler neck 2 and the protective tube 11 at their facing each other lateral surface ends with a Insertion chamfer 16 are provided.
- FIG. 2 differs from that of FIG 1, characterized in that the sealing ring 10th associated sealing surface on the free end face 17 of the Filler neck 2 is provided.
- the free end 14 of Protective tube section 11 projects beyond the free end 15 of the filler neck 2.
- the Filler neck 2 at a distance from another outer Protective pipe section 18 is surrounded, the free end of the 19th in the plane of the free end of the inner Protective tube section 11 is located and the together with the Filler 2 a receiving chamber 20 for the lid. 7 of the lid member 3 forms.
- Both receiving chambers 13, 20 have at their lower end a fuel passage 21st on.
